'attr' ignored by Active Directory?

[D.Kreft]

Are there any known issues of ActiveDirectory ignoring the 'attr' argument
of search() in Net::LDAP v.0.2701? I've got a script in which I'm talking to
an AD server and I say this:

    my $base = "OU=Foo,DC=Bar,DC=blah,DC=eek";
    my $scope = "sub";
    my $filter = "CN=*";
    my $attributes = ['description', 'cn'];

    my $msg = $ldap->search(base   => $base,
                            scope  => $scope,
                            filter => $filter,
                            attr   => $attributes);


But what is returned is all the records I'm lookin for, with *all*
attributes, not just 'description' and 'cn'.

Any tips?
